| | Autumn brings to mind images of cooler weather, leaves changing color and kids going back to school. It may also bring images of nasal congestion, sneezing and boxes of nasal tissue for those of us suffering from ragweed allergy. Ragweed pollen, which is released from ragweed mostly between August and October, is one of the most important causes of fall hay fever symptoms. | | All About Ragweed Allergy Ragweed grows just about anywhere, especially in fields, along the side of highways, and in vacant lots. This weed is especially common in the Midwestern region and along the East Coast of the United States, but it can be found in many other parts of the world, including Europe and Hawaii.
| Food Allergies and Ragweed Pollen The oral allergy syndrome (OAS) is a form of food allergy that is caused by a person having an allergy to particular pollen. The pollen, in this case ragweed pollen, has similar proteins (called profilins) found in a certain fruit, in this case melons, which causes a person to be allergic to both.
| How to Treat Fall Allergies Weed pollen is the main cause of seasonal allergy in the late summer and early fall. Depending on the area of North America, these weeds include ragweed, sagebrush, pigweed, tumbleweed (Russian thistle) and cocklebur. In certain areas of the world, some trees can pollinate in the fall as well.
